CHRISTIAN SHO-LL, OF MOUNT JOY, PENNSYLVANIA.

Letters Patent No. 110,078.y dated December 13, 1870.

IMPROVEMENT.' IN SASH-LOCKS.

The Schedule referred to in these Letters Patent and making partei' thesame.

M rvTo all lwhom 'it may concern Be it known that I,` CHRISTIAN SHOLL,of Mount Joy, in the county of Lancaster and State of Pennsylvania, haveinvented a new and improved Sash- Lock and Holder; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing and to theletters of reference marked thereon.

Drawing.

Figure l is a plan view of Iny improved sash-lock and holder, showingthe same when inortised into the casing of the window;

Figure 2 is a longitudinal section7 taken-on the line z s ot' fig. 1,showing the operation, and the manner of securing the spring plate, itbeing thrown Yin by the sash; and

Figure 3 is a transverse section, taken on the line x x of tig. 1, allthe parts being in their normal condition.

Similar letters of reference denote likeparts in each of .the ligures.

'lhis invention relates to an improved sash-lock and holder7 and isdesigned as an improvement upon the one for which Letters Patent weregranted to me on the 15th day of June, A. D.\1869; and

It consists in securing an inner plate of a sashholder to an outer andflanged face-plate by means of' a spiral spring acting over and securedupon a headed bolt secured to its outer face-plate, as will be herein-`after more fully described and set forth in the following specification.

A is the window-casing. within which my lock and holder are secured.

B represents the upper, and Bthe lower sash, having apertures and slotsat the side to register with the spring catches C O.

D represents the upper plate, which is mortised into and secured to thecasing A by screws d d.

Under the plate D is a plate, E, its lower endresting upon a squareflange, dl, and its -upper end having a catch, C, and thumb-button, e,by means of which button the catch G can be depressed when it is desiredto raise or lower the sash B.

'lwo pieces, Z2 and (Z3, are riveted or cast upon the inner surface of'the plate D.

A spring, F, is coiled around the pin d, which is headed to prevent thespring from coming olf, and the plate E.

The spring F will hold the plate E snugly against the plate D,unlessthrown in by the sash, as shown in Iig. 2.

Gr is the lower plate, adapted for the lower sash, and is precisely likethe upper plate, and operates in combination with like parts, with thisdifference: that the inwardly-projeeting ring surrounding thethumb-piece is onlitted,'and, instead of the thumb-button e, whichnecessarily must be made Hat, ornearly so, in order toallow sash Btopass overit, ithas a projecting thumbpiece, H, which protrudes throughthe inner strip or beadfot' the window, in order `that -the catch may brdepressed.

By iny present application the following advantages are obtained over myformer patent, viz:

First.' 'The catch spring and supporting-flange being upon a line withthe sash, the weight of the sash upon the catch is transmitted directlyupon the supporting- 'lange,` and the parts are less liable to get outof repair.

Second. rlhe s nine'. bein" made fast noon the iin or E: L V

for bolt, keeps the spring plate in position.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The spring F, permanently secured upon -the bolt il, in combination withthe plates E and D all and projecting thumb-piece H, all the parts beingarranged and constructed to operate together as shown and de' scribed,and for thel purpose set forth.

In testimony whereof, I have sinned my name to this speciication in thepresenceot 'two subscribing witnesses.

CHRIST. SHOLL.'
